Yes. You can easily have a few different Dashlane accounts on the same computer and keep all your data separate and private.
In fact, when several people share a computer, Dashlane helps each user keep their passwords, logins, IDs, credit cards, and secure notes private.
It's easy to switch from one account to another. When using the Dashlane web app, you can either click the extension and navigate to the last tab to find the Log out button or you can open the web app, click My Account and then Log out at the top left panel. This will log you out of your Dashlane account.
The next user can then log in by clicking the orange extension in the browser's toolbar and then on the arrow button next to the previous user's email address in order to choose their account from the dropdown menu.
Finally, don't forget to log out when you are finished using Dashlane on a shared computer!
